From CNN: The blast, at the city's Domodedovo Airport, killed at least
35 people and left more than 150 wounded, several
critically.

Experts say it is significant that those who masterminded
the attack chose to bomb the arrivals hall of the airport --
Moscow's busiest -- because it was an easier target than the
heavily-policed departures area.

The explosion occurred about 4:30 p.m. at the entrance of
the international arrivals section of Domodedovo Airport,
Itar-Tass said, citing a spokeswoman for the Russian
Investigative Committee, Tatyana Morozova.

The GCP event was set for 4:00 to 10:00, Moscow time.
The result shows Chisquare 21777.241 on 21600 df, for p =
0.197 and Z = 0.854.

It is important to keep in mind that we have only a tiny
statistical
effect, so that it is always hard to distinguish signal from
noise. This means that every "success" might be largely
driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect
can
be identified only by patiently accumulating replications of
similar analyses.
